Huh? This is not true.

    def foo(a, b, c): ...

This can be invoked as either `foo(1, 2, 3)` or `foo(c=3, b=2, a=1)`:

    >>> def foo(a, b, c):
    ...     print(f"{a=}")
    ...     print(f"{b=}")
    ...     print(f"{c=}")
    ...
    >>> foo(1, 2, 3)
    a=1
    b=2
    c=3
    >>> foo(c=3, b=2, a=1)
    a=1
    b=2
    c=3
    >>>
